Question

我正在尝试使用Google图表创建表，但是它返回表方法构造的错误。我看到了几个参考，但是我认为错误是jsapi库中给出的错误，因此google未定义。

这是我的html代码，如您所见，它很简单，我只是在尝试绘制表格，但总是向我返回这些错误

<html>
  <head>
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.2.1/jquery.min.js"></script>
    <script src="https://www.gstatic.com/charts/loader.js"></script>
    <meta name="layout" content="bootstrap">
  </head>
  <body>
    <div class="cabecalho"></div>
    <div id="table_div"></div>

    <script type="text/javascript">
      google.charts.load('current', {
        packages: ['bar', 'corechart', 'table'],
        callback: drawCharts
      });

      function drawCharts() {
        drawChartUsersActive();
      }

      function drawChartUsersActive() {
        var data = new google.visualization.DataTable();
        data.addColumn('string', 'Name');
        data.addColumn('number', 'Salary');
        data.addColumn('boolean', 'Full Time Employee');
        data.addRows([
          ['Mike',  {v: 10000, f: '$10,000'}, true],
          ['Jim',   {v:8000,   f: '$8,000'},  false],
          ['Alice', {v: 12500, f: '$12,500'}, true],
          ['Bob',   {v: 7000,  f: '$7,000'},  true]
        ]);

        var table = new google.visualization.Table(document.getElementById('table_div'));

        table.draw(data, {showRowNumber: true, width: '100%', height: '100%'});
      }
    </script>
  </body>

</html>

您尝试更换：

google.charts.load('current', {
    packages: ['bar', 'corechart', 'table'],
    callback: drawCharts
  });

  function drawCharts() {
    drawChartUsersActive();
  }

作者：

google.charts.load('current', {'packages':['table']});
google.charts.setOnLoadCallback(drawChartUsersActive());

这正是文档中所写的内容，所以也许行得通;）

类型错误google.visualization.DataTable不是构造函数
